• Digital Camera Lens Filter aslo can decrease the effective ISO of high-speed film and allow it to be used outdoors in bright situations
• To allow picture and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes that can cause overexposure
• Best Camera Lens Filter fit for SLR camera / digital camera / camcorder DV with a 58mm diameter lens
• Grade: ND8
• Material: Alloy & Resin
• Size: 58mm / 2.3in(Dia.)

Details:

• Neutral Density Lens Filter reduces the light passing through the lens without affecting the color Best suited for conditions of extreme light intensity - such as sunshine on snowy mountains or on the beach

• Fit for SLR camera / digital camera / camcorder DV with a 58mm diameter lens

What's the Camera Lens Filters:

• Camera lens filters still have many uses in digital photography, and should be an important part of any photographer's camera bag. These can include polarizing filters to reduce glare and improve saturation, or simple UV/haze filters to provide extra protection for the front of your lens

Lens Filter Type:

• The most commonly used filters for digital photography include polarizing (linear/circular), UV/haze, neutral density, graduated neutral density and warming/cooling or color filters
• Example uses for each are listed below:

Problems with Lens Filters:

• Filters should only be used when necessary because they can also adversely affect the image. Since they effectively introduce an additional piece of glass between your camera's sensor and the subject, they have the potential to reduce image quality. This usually comes in the form of either a slight color tint, a reduction in local or overall image contrast, or ghosting and increased lens flare caused by light inadvertently reflecting off the inside of the filter
• Filters may also introduce physical vignetting (light fall-off or blackening at the edges of the image) if their opaque edge gets in the way of light entering the lens (right example). This was created by stacking a polarizing filter on top of a UV filter while also using a wide angle lens-causing the edges of the outermost filter to get in the way of the image. Stacking filters therefore has the potential to make all of the above problems much worse

Neutral Density Lens Filter:

• Neutral Density filter or ND filter is a "grey" filter, it appears gray and reduces the amount of light reaching the film or sensor, but does not have an effect on color balance
• The purpose of standard photographic neutral density filter is to allow the photographer greater flexibility to change the aperture or exposure time, allowing for more control, particularly in extreme circumstances such as on a very bright day
• This filter can be used to prevent strong overexposure even when using a slow shutter speed. It's perfect for shooting in heavily-lit settings or for extended exposures. For example, when you use a slow shutter speed to capture a bright moving object, such as a waterfall, this filter is your best choice. See the pictures below for comparative shots of a waterfall taken both with and without the use of this filter. The ND Filter we offer is double thread with 2×, 4× and 8×(ND2 ND4 ND8) to indicate the amount of light a ND filter can reduce. Different neutral densities have different effects. You can use the filter individually or in any combination to meet your demand

ND Filter Have Four Main Uses:

• To enable slow shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, cars, seas, etc
• To decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
• To decrease the effective ISO of high speed film (i.e.: above ISO400) and allow it to be used outdoors in blight situations
• To allow cine and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes which would normally cause over-exposure

Note on Choosing a Filter Size for a Camera Lens:

• Lens filters generally come in two varieties: screw-on and front filters. Front filters are more flexible because they can be used on virtually any lens diameter, however these may also be more cumbersome to use since they may need to be held in front of the lens. On the other hand, filter holder kits are available that can improve this process. Screw-on filters can provide an air-tight seal when needed for protection, and cannot accidentally move relative to the lens during composure. The main disadvantage is that a given screw-on filter will only work with a specific lens size
• The size of a screw-on filter is expressed in terms of its diameter, which corresponds to the diameter usually listed on the top or front of your camera lens. This diameter is listed in millimeters and usually ranges from about 46 to 82 mm for digital SLR cameras. Step-up or step-down adapters can enable a given filter size to be used on a lens with a smaller or larger diameter, respectively. However, step-down filter adapters may introduce substantial vignetting (since the filter may block light at the edges of the lens), whereas step-up adapters mean that your filter is much larger (and potentially more cumbersome) than is required
• The height of the filter edges may also be important. Ultra-thin and other special filters are designed so that they can be used on wide angle lenses without vignetting. On the other hand, these may also be much more expensive and often do not have threads on the outside to accept another filter (or sometimes even the lens cap)

How to Uses Lens Filters With Digital Video Cameras

• You can utilize the effects of lens filters with digital video (DV) cameras if you know something about the way these filter lenses work. For instance, you'll soon discover that the old filters don't work the same with the new DV cameras. Auto focus cameras are renowned to reset the focus on to the filter rather than what you're trying to capture. So, you'll need to know how to weigh the lenses and the DV cameras for compatibility, and you'll need to know what you want from the filters before you invest. In digital video you can't be safe by hedging an expensive camera with a cheap lens, or vice versa. You'll need to consider what really works--and don't trust the larger dollar for the better, be it the lens or the DV camera. Of course, if you are really looking at taking DV seriously as a long term hobby or profession, you could gradually build up your lens and camera collection a little over time.
• Instructions
• Know your camera's limitations and how to improvise. Determine what kind of camera you have. De rigeur is a good lens for Panasonic's AJ-D215.
• Determine the type of lens that will compensate for most of your videoing needs. For example, if you are going to spend your time video capturing people at the beach, De Rigeur is a good filter for skin tones. The De Rigeur filter is a good complement to a DV like Panasonic's AJ-D215. However, Sony's DSR-PD100A takes some pretty good DV footage and doesn't need the filter for skin tones. You might also consider Glimmerglass. Glimmerglass reduces contrast, and thus is good for filming people.
• Consider acquiring a diffusion filter if you're shooting small format DV.
• Know that Black Diffusion FX makes your digital videos look like they haven't been filtered at all. This filter makes digital video look like pro Hollywood film.
• Remember to consider the compatibility between the camera and the film, as well as knowing the limits of your equipment. Don't be intimidated by the diversity of DV cameras and filters. Build your hobby or career over time. Your patience and study will prevail.
